Fully Automated High-Capacity Pig Feed Pellet Production Line | Turnkey Solution for Large-Scale Farms & Feed Mills

Industry Challenges & Our Solution

Against the backdrop of rapidly expanding large-scale farming operations, feed processors are confronting multiple challenges: rising labor costs, inconsistent feed quality, high energy consumption of outdated equipment, and insufficient flexibility for multi-species production switching. In response to these pain points, we present the SYLH Series Fully Automated High-Capacity Pig Feed Pellet Production Line – a comprehensive turnkey solution that integrates the entire process from raw material intake to finished product packaging, tailored for large-scale pig farms and commercial feed manufacturing enterprises.

Solution Core Architecture

Fully Automated Production Workflow

This solution integrates raw material cleaning, precise grinding, intelligent batching, high-efficiency mixing, high-temperature conditioning & pelleting, cooling & screening, and automatic packaging into a seamless fully automated production line. Designed with a modular approach, the complete closed-loop system from raw material receiving to finished product packaging ensures synchronized operation across all stages, delivering enhanced production efficiency and consistent product quality.

Raw Material Receiving & Cleaning Module – Incoming materials first pass through a pre-cleaner and permanent magnetic drum to effectively remove impurities such as straw, stones, and tramp metal, protecting downstream equipment. Powder and pelletized raw materials are fed through separate inlets to prevent cross-contamination.

Grinding Module – Equipped with high-efficiency hammer mills, variable-frequency feeders, and pulse dust collection systems, this module grinds corn, soybean meal, and other ingredients to the optimal particle size for pelleting. Grinding fineness directly affects mixing uniformity and pellet formation rate, making it a critical factor determining feed digestibility.

Batching & Mixing Module – A computer-controlled automatic batching system achieves macro-ingredient dynamic accuracy of ≤ ±0.1% and micro-ingredient accuracy of ≤ ±0.01%, ensuring consistent nutritional ratios in every batch. The twin-shaft paddle mixer rapidly achieves high uniformity and can incorporate liquid ingredients such as oils and fats to improve palatability and energy density.

Pelleting Module – The core of this solution features the SYLH Series ring-die pellet mill paired with a steam conditioner. Materials are subjected to high-temperature steam conditioning at 85°C+, enabling starch gelatinization and protein denaturation while effectively eliminating Salmonella and other pathogens. The high-precision gear transmission design significantly increases output by approximately 20% compared to belt-driven systems.

Cooling & Screening Module – Freshly extruded pellets emerge at high temperature and moisture content, requiring rapid cooling via a counterflow cooler to bring them to ambient temperature and safe moisture levels, ensuring pellet hardness and storage stability. The cooled pellets then pass through a grading screener to remove fines and substandard pellets, guaranteeing uniform finished product quality.

Packaging Module – Fully automatic定量 packaging machines with sewing and conveying equipment achieve precise weighing and rapid sealing, improving finished product dispatch efficiency.

Key Technical Advantages

❶ High Capacity & Operational Stability
The SYLH Series covers capacities from 1 to 20+ tons per hour, accommodating diverse needs from small feed mills to large-scale production bases. The PLC centralized control system provides real-time monitoring of equipment status and production parameters, one-touch recipe switching, and automatic fault alarming, ensuring continuous and stable production.

❷ Precise Batching – Consistent Nutritional Quality
Computer-controlled batching system with macro-ingredient dynamic accuracy ≤ ±0.1% and micro-ingredient accuracy ≤ ±0.01%, ensuring highly consistent nutritional profiles across all batches.

❸ Superior Pelleting Performance
SYLH Series ring-die pellet mills feature high-precision gear transmission for smooth, reliable operation. Steam conditioning at 85°C+ fully gelatinizes starch while effectively eliminating pathogens.

❹ High-Quality Finished Pellets
Pellet formation rate ≥ 98%, with smooth surface, moderate hardness, and low fines content for easy storage, transport, and feeding. The high-temperature pelleting process effectively eliminates anti-nutritional factors in soybean meal and reduces the risk of digestive diseases.

❺ Flexible Multi-Species Production
By changing ring dies of different hole diameters and adjusting process parameters, the line can produce feed for pigs, chickens, ducks, cattle, sheep, fish, and more. Ring die hole sizes can be customized by target species: piglet feed 2-3mm, grower pig 3-3.5mm, finishing pig 4-6mm.

❻ Energy Efficient & Low Operating Costs
Main motors adopt high-efficiency energy-saving designs with optimized overall energy consumption. Pulse baghouse dust collection systems ensure emissions meet environmental standards. The entire line requires only 3-5 operators, saving over 60% in labor costs compared to traditional models.

❼ Modular Compact Design
Small footprint with low initial capital investment. One machine, multiple applications – maximizing equipment asset utilization.

Application Scenarios & Customization Options

This solution is applicable to the following specific scenarios:

• Large-Scale Pig Farms – Self-Supplied Feed – Farms with 10,000+ head annual output equipping their own feed production workshop

• Commercial Feed Processing Enterprises – Mass production of commercial pig feed for the market
